T() ALL WIIOM I'l MAY CONGERN:

.3e it known that I, 'lLLI-.Lu W. Slt-NMSP, ol-` Greenland, iu the county of Outonagou, and State ot Michigan, have invented a new and useful improvement. in Jigging Machines; and I (lo hereby declare that the i Following a full, clear, and exact description thereof', which will enable others skilled in the art to make and use thc same, reference being had to the accon'ipanyiug drawings, formingpart of this specification, in which- .Figure 1 is a vertical section of my improved jigging machine, taken in the plane of the line .fc at', tig. 2. 'Figure is a plan or top view. Figure 3 is nu enlarged sectional view of a detail cut iu the plane of' the line l/'y, iig. -L y Figure il is a sectional view otl the saine/part cut in the plane of the line z z, fig. il. Figure 5 is a sectional view of the raggiug-box, cut iu the plane of the line 'w w, fig. l. Similar letters of reference indicatclike parts. o This invention relates to improvements in jigging machines, and consists in novel arrangements and devices for washing the ores of copper, lead, silver, and other mctals'after they have been pulverized in a stamp-mill, and separating the minerals or metals frontthe roel: and earthy substances associated with them in the ore. The machinery in general use for jiggiugores is more or less expensive, and complicated in constructiou, and imperfect in operation. i\l )'i11i1 i1o\'cd jigging machine is simple, cheap, and eilicicnt; the crushed orcs are rapidly and thoroughly washed, and the minerals or metals separated clean from the roel: and earthy parts of the ore. This machine may be applied to ores of all descriptions.

The drawings represent a double machine, that is to say, two machines together, any number of which may be placed side by side in the same manner, each separate machine being constructed and operated alike. The Following description, thert'lforc, applies to only one machine or part having a distinct and independent operation;

A represents a water-box for washii g or iigging the pulverized ores. The ground plan of the main compartment is rectangular and nearly square, as shown by tiff. 2. The top and bottom are level, and the front side is made sloping back from thc top to the bottoni. At the upper part of the backl of the main box is a plungerbox, B, communicating with it by a wide opening or throat, a, and on the top is a wire sieve, b, placed several inches below the upper edge of the box. The floor c of the plunger-box B inclincs forward, and is extended to form an inclined false bottom, t", in the main box A, iu which is a. narrow opening or throat, d, that runs across the box to form a separate compartment, A', in the hack part, into which the water for washing the orcs is conveyed by a pipe indicated in red from a source above the level of the machine to keep it always full of water, as shown in tig. l. lhc main compartment of the box A is provided with a discharge pipe, e, at the bottom in front, and the smaller compartment A with a discharge pipe, c', at the back. A plunger, C, is pivoted or hinged on one side to thc front part ofthe plunger-'box B level with the top of thc main box box A, and is suspended at the back part hl: an adjustable bail or bow, g, which straddles an inclined apron, D, that sets above the box B. The bail g is hung to a crank-shaft, t, running in the caps d. of' the frame-posts al al, by which the plunger C is operated. A rake, r, is placed on the sieve b, and receives a sliding motion forward and back by means of a counter-shaft, Z, with which it has a crank connection, and that is turned by a band, m, running from thc shat'tt over pulleys m1, m2. The pnlvcrized orc is conveyed to the apron D in the ordinary way, and passes thence on to the sieve Il, where the rake 7c agitates and loosens the mass and cuts the slime in its passage over the sieve, while at the same time the plunger D, which is lifted by the rotation of the crank-shaft 7l, rises and falls suddenly in the plunger-box D, and thus produces a pulsating movement in the water in thc box, forcing it up through the sieve intermittently, and suspending the lighter portions or earthy waste matters which are carried forward by the current of water to the tail of the machine, while the heavier or metallic portions either settle on the bottom of the sieve or pass through it into the box. .lhe coarser parts of the mineral that will not pass through the sieve arc allowed to accumulate to a certain depth on the sieves, and form what is called the ragging or bottom, which, by its density, aids -in supporting and carrying oft' the refuse or waste sands. In' my machine the ragging is kept at the required depth by its own operation, the surplus being discharged by means of a self-regulating device placed at the tail of the machine, which allows it to pass into a tagging-box in front.

E is a closed lagging-box attached to the front side or tail end of the, main box A. The raggingboii E is a. flat, three-cornered box set on ythe front side of the main box A, with one ofits sides level with the top thereof, and one of its corners pointing downwards, as shown in lig. 5. At the bottom of the lagging-box is a discharge pipe, n, iig. 5, and at' the top is a narrowslot, u', opening into a; guard, F, placed just inside of the upper edge of main box A, and having its lower edge slightly raised above the sieve Z) to allow the passage of the eoarsei' mineral under it to a self-acting gated), that leads to the opening n in the ragging-box. The gua-rd F is open above and below, und is triangular in shape, one corner .pointing towards the rake to act as a guard and guide for carrying off the waste, and allowing only the heavy mineral to pass under it to the lagging-box. '.lhe gate p is hung with a eounterbalanee weight and lever, g, attached, which keep it closeduntil the resistance of the counterpoise is overcome by the accumulated pressure of the mineral, when it opens and the mineral passes into'the ragging-box. his automatic operation of the gate is constantly repeated, and.

thus the ragging-bed on the sieve is self-regulatedat the required depth. The' coarse mineral is drawn off from the ragging-box through the discharge pipe vz, The gate p is shown open in fig. 4.

The heavy and liner metallic portions o'f lthe pulvcrized ore pass through the head of the sieve YI; Vand l'all on the upper part of the floor c', and run down until they meet the current of water rising up from the supply-box A through the passage or 'throat (I, which eleanses the mineral of any refuse sands so that it falls through the opening d into the box Af, andissues through the discharge pipe e at the back of the machine in a highly purified condition. The lighter portion is carried forward in the main box and finds exit through the discharge pipe c in front. Y

The whole combined operation of the several parts that have beendescribed iu their construction and operation separately will be readily understood.

Having thus described my invention, what I elaim as new, and desire to secure by Letters Patent,y is

1. I claim the main box in combination with the plunger-box B, having a water-passage or throat, a, connecting them, and divided into two compartments, with the water-passage lbetween them, and discharge pipes e e' leading from them, arranged and operating substantially as and for the purposes herein described.

2. The plunger C, pivoted or hinged at one side, in combination'with the box B, the main box A, and the sieve b, arranged and operatingsubstantially as and for the purposes specified.

3. 'lhe'eombination of the closed ragging-box E attached to the front side of the main box A, the self-` regulating gate p, and the guardF, constructed, arranged, and operating substantially as vand for the purposes set forth.

4. The rake t, iu combination with the counter-shaft l, the crank-shaft L, and the sieve-b, arranged and operating as and for the purpose described.

'lhe combination and arrangement of the main box A, the plunger-box B, the plunger C, the hail g, the apron D, the rake k. the guard F, the gate p, and the lagging-box E, substantially as and for the purposes herein described. f
